Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an outer casing structure for an induction heating cooker.

BACKGROUND OF THE INVENTION Conventionally, this type of induction heating cooker has a structure as shown in FIGS. 4 and 5.

That is, the main body of the induction heating cooker (hereinafter referred to as the main body).

) is provided with a flange λ at the upper end of the outer casing side wall, and this 7
The lunge 2 is engaged with the mounting base 3 to support the weight of the main body via the connecting body jA.

Further, the tip of the flange 2 is formed with an upwardly rising portion. Further, on the outer periphery of the top plate having the induction heating coil jB on the back surface of the top surface of the main body l, there is a top plate having a flange 6 bent vertically, with the outer periphery facing outward as well as the flange of the outer casing of the main body. A frame 7 is provided ◇ And, ventilation is provided by the gap a formed between the upright part of the flange of the main body outer casing, the top plate, and the frame flange 6, and the hole 2 of the flange 2. This serves as a ventilation path for the outlet.

The exit passage is formed through the hole J'A-2 in the bottom of the main body l, the hole J'A-2 in the connecting body jA, the upper horizontal part of the connecting body jA, and the flange 2.
The space between the rising part ≠ the tip of the

Problems to be Solved by the Invention However, in such a structure, the ventilation path consisting of the upright part of the flange of the main body outer casing, the top plate, and the frame flange B is as shown by the arrow in Fig. 5. Since the cooling air flows while drastically changing its direction from upwards in the raised part of the flange 2 to downwards in the holes 2-/ in the flange 2, there is a problem in that the ventilation resistance increases and the cooling efficiency inside the main body l decreases. Ta.

Furthermore, if there is boiling over on the built-in table 3 or the top plate j,
There is a problem in that boiled boiled water enters the inside of the assembly base 3 through the minute gap between the flange 2 of the outer casing of the main body and the upper surface of the assembly base 3 and becomes dirty.

Therefore, the first object of the present invention is to reduce ventilation resistance and improve cooling efficiency.

, The second purpose is to make it easier to clean spills inside the built-in stand.
It is to be.

Means for Solving the Problems In the present invention, the tip of the flange at the upper end of the side wall of the outer casing of the main body is raised to form a raised part, and a top plate having an induction heating coil on the back surface is fixed to the upper part of the outer casing of the main body. The main body is constructed by providing a top plate and a frame flange that cover the outer periphery of the top plate, and configuring the tips of the top plate and frame flange to be outside of the raised part of the flange at the upper end of the side wall of the main body outer casing. The flange of the main body is placed on an assembly stand, the side wall flange on one side is configured to create a gap between the assembly stand, and the lower part of the side wall flange on one side is configured to form a gap between the assembly stand and the side wall flange on one side. A built-in casing having a similar shape to the main body outer casing having large dimensions outside the main body is fixed to the built-in base, and the main body is inserted into the built-in casing. The flange is placed on the mounting base.

Function: The induction heating cooker of the present invention has the above-mentioned structure, which reduces changes in the direction of ventilation of the ventilation passage for cooling the inside of the main body, reduces ventilation resistance, and improves cooling efficiency.

Further, boiled spills that enter through the gap between the flange of the outer casing of the main body and the top surface of the mounting base collect in the container-shaped built-in casing provided on the mounting base, making it easy to clean the boiled spills.

Embodiment FIG. 1 is a perspective view of a first embodiment of the induction heating cooker of the present invention, and FIG. 2 is a sectional view of FIG. 1.

In FIGS. 1 and 2, the upper end of the outer casing of the main body 10 includes a first flange l3 that engages with the upper surface of the mounting base l2, and a first flange l3 that is formed above the flange l3 and engages with the assembly base l2. A second flange l≠ that does not match is formed. The tip of the first flange l3 is erected upward. Upper part/! is formed.

In addition, the outer periphery of the top plate /6 which has an induction heating coil /AB on the back surface of the main body//// is vertically aligned with the outer periphery of the outer casing of the main body 7/3, lμ. A Tensaka frame /r having a flange /7 is provided. Further, the second flange /l of the main body outer casing, which does not engage with the installation base l2, is provided with two protrusions /ta whose lower ends engage with the installation base l2.

Next, the operation of the configuration of the first embodiment of the present invention will be explained.

The ventilation path for internal cooling of the main body passes through the gap b between the second flange l≠ of the main body outer casing and the assembly base lλ, as shown by the arrow in FIG. After being guided inside and passing through the hole //-/ at the bottom of the main body l/ to cool the inside of the main body ii, the connecting body /9-/ of the top plate /6 and the main body outer casing l is connected.
, the first flange l3 of the main body outer casing, the top plate, and the frame l7
The air is exhausted through the gap between the flange l1r and the flange l1r.

At this time, the air passage between the second flange l≠ of the main body outer casing and the assembly base l2 does not have a large change in air direction, such as turning upward and then downward, and the airflow resistance can be reduced. It has the effect of improving cooling efficiency.

Next, a second embodiment of the present invention will be described.

In the second embodiment shown in FIG. 3, the assembly base l2 of the main body // has a similar box-shaped container-shaped assembly frame larger in size than the outer casing of the main body // and having a gap C. A body 20 is provided.

The ventilation passage in the second embodiment is the same as in the first embodiment.
Between the gap built-in frame 20 and the main body outer casing 1/, the hole in the main body outer casing, the hole in the connecting body, and the first flange l3 in the main body outer casing, Air is exhausted through the gap between the top plate frame/7 and the flange l♂.

In such a configuration, even if the liquid boils down on the top plate /t of the main body /l or on the assembly base /2, the liquid will accumulate in the assembly frame 20 when it enters the interior of the assembly base /2. Cleaning of boiled water can be done by removing the main body /1 and wiping the assembly frame 20, so cleaning can be facilitated and the inside of the assembly table /2 will not be soiled.

Effects of the Invention In the present invention, a part of the flange on the upper part of the outer casing of the main body has a protrusion so that it does not engage the entire assembly base, and the gap between the protrusions is used as a ventilation path, reducing ventilation resistance. can improve cooling efficiency.

In addition, since the present invention has a container-shaped assembly frame that is larger in size than the outer casing of the main body, the inside of the assembly base will not become dirty due to boiling spills, and it is easy to clean spills. It produces effects such as being able to.
